![### Problem 2
Another of the doohickeys analyzed by the [Redacted] Mechanism Enthusiast Club is the crank-slider shown. The crank is turning at a constant \(\omega_{AB} = 20 \, \text{rpm}\) counterclockwise. The dimensions are \(L_{AB} = 200 \, \text{mm}\), \(L_{BD} = 150 \, \text{mm}\) and \(L_{BC} = 230 \, \text{mm}\).
Using the methods shown in class that require diagrams, determine the acceleration of points A and D, providing magnitude and direction.
#### Diagram Explanation
The given diagram illustrates a crank-slider mechanism with the following components and dimensions:
- **Crank (AB):** This rotates about point A and is shown in a vertical orientation. The length \( L_{AB} \) is 200 mm. The angular velocity \( \omega_{AB} \) is 20 rpm in the counterclockwise direction.
- **Link (BD):** This links the slider at point C and the mechanism at point D. The length \( L_{BD} \) is 150 mm.
- **Slider (BC):** The slider is connected to the ground at point C and touches point B on the link. The length \( L_{BC} \) is 230 mm.
The calculations involve determining the accelerations of points A and D using kinematic equations and graphical methods taught in class. Make sure to provide both the magnitude and direction for these accelerations.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fd7b1f94a-aeb1-4e21-a353-b14674dcbf02%2F60836ecb-cef6-4003-8160-cc033420f881%2Fwtlp1p_processed.png&w=3840&q=75)
